Figure 6‐13: FGR Burner with VFD and Air Damper on Blower Inlet
In summary, the arrangement shown in Figure 6‐13 is preferable for the following reasons:
1. Better repeatability of FGR flow with slight pressure changes from P1 to P2.
2. Greater adjustability of the FGR to air ratio when trimming.
3. The ability to draw more FGR at lower firing rates.
